Lesson 1.6 Angles and Setup Activity

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What are congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

How do you determine if two angles are complementary?

Back

If the sum of the measures of the two angles equals 90 degrees, they are complementary.

Front

How do you determine if two angles are supplementary?

Back

If the sum of the measures of the two angles equals 180 degrees, they are supplementary.

Front

What is the equation to find the measure of an angle if it is complementary to another angle?

Back

If angle A is complementary to angle B, then A + B = 90 degrees.

Front

What is the equation to find the measure of an angle if it is supplementary to another angle?

Back

If angle A is supplementary to angle B, then A + B = 180 degrees.

Front

If two angles are congruent, what can be said about their measures?

Back

If two angles are congruent, their measures are equal.

Front

What is the relationship between complementary angles and right angles?

Back

Complementary angles together form a right angle (90 degrees).

Front

What is the relationship between supplementary angles and straight angles?

Back

Supplementary angles together form a straight angle (180 degrees).
